<h1 class="topictitle1">Restoring Cloud Servers</h1>
<div><p>This section describes how to restore a cloud server resource to the original or a new location after the cloud server has been backed up, when the cloud server is damaged.</p>
<div class="section"><h4 class="sectiontitle">Context</h4><p>The <span>OceanProtect</span> allows you to restore cloud disks to the original or a new location using backup copies, reverse replication copies, archive copies (data cannot be restored to the original location using archive copies of replication copies), or replication copies (data cannot be restored to the original cloud server using replication copies). Cascaded replication copies and their archive copies cannot be used for restoration to the original cloud server.</p>
<ul><li>Restoration to the original location<p>Restore data to the cloud server in the current project.</p>
</li><li>Restoration to a new location<p>Restore data to another cloud server or a new cloud server on another platform or in another project.</p>
</li></ul>
</div>
<div class="section"><h4 class="sectiontitle">Precautions</h4><p>A maximum of 24 disks can be mounted to a host where the client is installed. Therefore, if 24 disks have been mounted to a host where the client is installed during restoration, the system will execute the restoration job when there are idle slots.</p>
</div>
